Police are investigating the brutal beating Sunday morning of Bryan Higgins, 31, on Church Street between Market and Duboce streets. Video from Muni and surrounding businesses captured the assault. Friends say Higgins was part of the radical faerie community.

The man who was found brutally beaten in the Duboce Triangle area Sunday and was later identified by family remains in the hospital with critical injuries, but family and friends say they are considering taking him off of life support.

Police reportedly have evidence from surveillance footage from Muni and nearby businesses that captured the attack and are investigating it as a case of attempted murder and assault with a deadly weapon.

It's unclear what the deadly weapon was.

The victim, Bryan Higgins, 31, also known as Feather Lynn, was discovered critically injured about 7:10 a.m. Sunday on Church Street between Duboce and Market streets and was taken to the hospital, police said Monday.

At San Francisco General Hospital, it was discovered that Higgins had no identification on him, so hospital officials put a call out to the media to spread word of his case in the hopes that someone would recognize him and identify him.

A neighbor recognized him and contacted his family, who went to the hospital and identified him.

Friends of Higgins said he was part of the radical faerie community in San Francisco and that he worked at Rosenberg Delicatessen in the Castro. An employee at the deli said he could not comment over the phone Tuesday.

They also said it was the third time that a person involved with the radical faerie community has been assaulted within the past year, although did not believe the attacks were related.

Radical faeries generally tend to be gay men looking for a spiritual dimension to their sexuality, according to the website radfae.org.

Police have not said whether they will be investigating the incident as a hate crime.

On Monday, police said they were investigating the case as an attempted murder and assault with a deadly weapon.

On Tuesday, friends and family held a ritual at the hospital for the victim to help set his spirit free.

They were tentatively planning a vigil in his honor today at 3:33 p.m. at Duboce Park, not far from where he was found.

At around that time, Higgins' family is also tentatively planning to remove the man from life support.

It was unknown the circumstances of the attack, including where he was coming from or where he was going.

Police have a vague description of the suspect, a white man in a dark-red hoodie, and informed family and friends that surveillance footage from Muni and nearby businesses reportedly caught the attack.
